This video from ASAP Science is pretty awesome!
USE HEADPHONES AND FOLLOW ALONG!
How high can you hear? Take this ‘test’ to see how old your ears are!
Comprehensive Hearing Evaluation
The audiogram consists of three parts, pure tone air, bone conduction, and speech testing. All three parts are conducted in a comfortable sound booth. The instructions will be clear, and the test will be brief as possible to provide the necessary information. Pure Tone Air – Soft foam inserts are placed in the ear canals. You will hear a series of sounds and will indicate when you hear each one by pressing a button. The sounds will vary in pitch from deep bass to high treble, measured on a frequency scale from 250 to 8000 Hz. This range is the most important for everyday sounds and speech. The volume of each sound is adjusted until the softest level for each sound is detected. This level is called your “threshold.” Speech Testing – If your thresholds indicate a hearing loss is present, speech testing will be conducted. Here you will be asked to listen to and repeat a series of familiar words which become softer and softer. This will help determine your speech threshold, the softest level that you can recognize familiar two syllable words, like “baseball” or “hotdog.” Words will also be played at a comfortable, conversational level to determine your word recognition score, how well you understand speech if the volume is appropriate for your needs. If necessary, other tests can be preformed to evaluate how well you hear in difficult or noisy environments. Bone Conduction – The soft foam inserts are removed. A head band is placed over the top of your head to hold a small instrument (bone oscillator) on the Mastoid Bone directly behind the ear. Four of the frequency sounds tested previously during Pure Tone Air will be sent directly to the inner ear (Cochlea) via bone conduction. If the Bone Conduction threshold is significantly better than the Pure Tone Air thresholds it indicates that something is hindering the sound to travel down the ear canal as it should. Several factors could contribute to this and a referral to an ENT doctor would be required. Once we have interpreted the results of your hearing evaluation and explained them to you clearly, it’s time to develop a plan to help you rediscover your hearing and reconnect with the important things you might have been missing. This is where a spouse, family member, or a friend may be helpful. Hearing devices may be recommended. Fortunately, hearing devices can help most people and today’s choices are easy to try, often right in our office on the same day of your hearing evaluation.
